Question

Quizplus · Accepted Answer

Isotopes are atoms of the same element that have the same number of protons (and, therefore, the same atomic number) but different numbers of neutrons. This results in isotopes with different atomic masses. The number of electrons in an atom can vary as well, but this does not affect its status as an isotope. Therefore, option D is the correct choice.
